A US woman who shot and killed her husband and two adult children before taking her own life is thought to have committed the shocking crime as a result of being ostracised from the religion she was raised in.

Every time I tell a mate I’m doing a story on cryptocurrency, they invariably ask me the same two questions: should they invest their own hard-earned money, and which cryptocurrency will get them a Lamborghini/yacht/island quickest?

Police gun seizures continue in SA

A South Australian man has been charged after police raided his property and seized nine guns and a crossbow.

Acting on a tip-off, police raided a Salisbury East property on Thursday morning, allegedly finding six rifles, three handguns, ammunition and a crossbow hidden under floorboards in the house.

A 64-year-old man was charged with nine counts of failing to store a firearm correctly, nine counts of possessing a firearm without a license, nine counts of possessing an unregistered firearm, failing to safely store ammunition, and possessing a prohibited weapon.

He was granted bail to appear at Elizabeth Magistrates Court on June 26.

The seizure was a significant one, bringing to 1,900 the total number of firearms seized in the state in the past year, said SA Police acting assistant commissioner Michael Cornish.

He said he wouldn't be surprised if a number of the weapons turned out to be stolen.

"Some of them may never have been registered. They may have been in the illicit market for decades," he told reporters in Adelaide.

"Firearms can exist for in excess of 100 years, so some of those may never have been on our radar before. It's a great find in that regard."

An amnesty held late last year resulted in 3,000 firearms being surrendered, Mr Cornish said.

On Friday, police nationwide will launch a two-week blitz on illegal firearms and their suppliers, with hundreds of police standing by to receive anonymous tip-offs from the public.

Police have been concerned about the growing number of guns discovered by officers on routine patrols, widespread theft of firearms from rural properties, and a failure among licensed gun owners to safely secure their weapons.

"Most firearm owners are responsible, but we're asking all of them to make sure they are properly secured and registered. This makes it much more difficult for criminals to steal firearms from the community," Mr Cornish said.
